I think we have all come to realize the SFDA follows no time line. I'm sure they will get back to Calypte whenever they "feel like it". According to an earlier statement:
'Once we submit any requested materials to the CDE, they have 30 working days to process the supplemental materials and make a decision (accept, reject, request additional info, or schedule for later review)'
So if they submitted in early May, this would come to somewhere in mid June...but like I said who knows with the SFDA.
